If you are refering to the silver can, that is not a capaciter, but an oscillator for the clock (time and date clock that is) I would hazzard a guess.
When you replaced the battery are you sure you did not damage the print around the pads? No solder escaped elsewhere, like tiny blobs or hair like strands of solder?

Also make sure the bottom of the battery is not sitting on anything, and is the same size (diameter) as the old battery so as the clearence around it is sufficient.
Did you use an anti-static wrist strap etc..?
When I say no damage to the print, I mean check that the iron tip did not dig it's way into the board, as looking at pictures of the back of a Blizzard there are at least two tracks within the PCB it's self (being multi layered) near the one of the battery terminals.

And the oscillator should give continuity between both "legs", right?


That I don't know mate. Just be a bit careful though with using the multimeter around the PCB when using the 'Ohm' or 'Continuity' setting. The meter will be putting out a small voltage to get the reading, and the wrong voltage in the wrong place...
In all likelyhood though, I would not have thought this is faulty.

Can you post a clear picture please of the CPU oscillator that is in the board. Lets make sure that it's correctly oriantated.

Looks like it correct.
Is that paste on the PCB? You might want to remove all traces of that as I am sure it's conductive. Can someone confirm this?
